[alsa-devel] [PATCH v2 0/2] ASoC: dpcm: fix BE dai not hw_free and shutdown

[KaiChieh Chuang]

These two patch is to solve problem found
in the case of one BE is used by multiple FE.

The error log "ASoC: Unable to apply rate constraint"
will happen when be_substream->runtime is use after free.
Which is due to BE not being hw_free/shutdown correctly.

Also to resolve fe_substream->runtime is not
constrained by BE dai symmetry property.

v2:
    remove flag condition
